CONFIG_GPIO_NOVALAKE: Intel Nova Lake GPIO-signaled ACPI events support

General informations

The Linux kernel configuration item CONFIG_GPIO_NOVALAKE:

• prompt: Intel Nova Lake GPIO-signaled ACPI events support
• type: tristate
• depends on: ( CONFIG_X86 || CONFIG_COMPILE_TEST ) && CONFIG_ACPI
• defined in drivers/gpio/Kconfig
• found in Linux kernels: 7.1-rc+HEAD
• modules built: gpio-novalake-events

Help text

Select this to enable GPIO-signaled ACPI events support on platforms with the following SoCs:

- Intel Nova Lake

This driver adds support for new mode of handling platform events, through the use of GPIO-signaled ACPI events. Main purpose is to handle platform IRQs that originate in PCH components, for example interrupt triggered by Power Management Event (PME).

This driver, at this time, is not required to handle platform events. Listed platform(s) will stay in legacy mode, handling ACPI events as in previous generations. However, future platforms will eventually switch to new handling mode, requiring this driver to run events properly.

Driver supports up to 128 GPIO pins per GPE block.

To compile this driver as a module, choose M here: the module will be called gpio-novalake-events.
